Two weeks ago I went to one of my favorite deal sites, Living Social and purchased two weekend passes for a fun center in Newtown Square, PA called Jumpers. The pass was $6 for a weekend visit, plus a bottle of water and a snack. The pass was unlimited in terms of the hours of play. My kids played for almost two hours.
The kids had so much fun, although there were multiple parties being held it was a lot of fun. The facility has about 3 oversized inflatable moon bounces. I think I would prefer if there was a specific area for bigger kids. Some of the bounces were a little overcrowded with older children and this made bouncing a little bit scary for smaller kids. Obviously, my kids were over it as they are asking to go back soon.
